4D flow技术在腹部应用的研究进展

Application and Research Progresses of 4D Flow MRI in Abdomen

腹部动脉、静脉或门静脉系统形态及功能改变与很多腹部疾病有关,因此腹部血流动力学的综合评估对很多临床诊治至关重要,但由于解剖学、正常生理学和各种病理异常的巨大复杂性而面临挑战。四维血流核磁共振(4D flow MRI)非常有效地结合了非侵入性及侵入性检查(如超声,血管造影,CT等)的优点,是一种新型的相位对比MRI技术,能全面无创的可视化和定量的评价腹部不同血管区域和器官中的腹部血流,同时有助于了解病理生理机制,是一种非常有潜力的全面评估腹部循环的技术。本文主要对4D flow技术在腹部中的应用进展进行综述,为临床对疾病的诊断和治疗以及科研提供新的方向和思路。

The morphological and functional changes of the abdominal arterial,venous,or portal venous system are related to many abdominal diseases.Therefore,a comprehensive assessment of abdominal hemodynamics is essential for many clinical diagnosis and treatment.However,due to the huge complexity of anatomy,normal physiology and various pathological abnormalities facing challenges.Four-dimensional flow MRI(4D flow MRI)effectively combines the advantages of non-invasive and invasive examinations(such as ultrasound,angiography,CT,etc.)And quantitative assessment of abdominal blood flow in different vascular regions and organs of the abdomen,while helping to understand the pathophysiological mechanism,is a very potential technology for comprehensive assessment of abdominal circulation.This paper mainly reviews the application progress of 4D flow technology in the abdomen,and provides new directions and ideas for clinical diagnosis and treatment of diseases and scientific research.
